NEW ZEALAND Patents Act 1953 COMPLETE SPECIFICATION "DRAWER GLIDE MOUNT." We WESTINGHOUSE ELECTRIC CORPORATION, Westinghouse Building, Gateway Center, Pittsburgh, Pennsylvania 1522 2, United States of America, a corporation organized and existing under the laws of the Commonwealth of Pennsylvania, United States of America, do hereby declare the invention, for which we pray that a Patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement:- ^ (Followed by 1A.) 2 043 6 6 ■ S DRAWER GLIDE MOUNTS This invention relates to drawer glide mounts and more particularly to the mounting of drawer glides to the side wall of a drawer cabinet, i ^ A typical drawer glide is disclosed in U.S.

Patent Specification No. 3,205,025 (Jordan) and basically j includes an inner rail mounted to the drawer and an outer I rail mounted to the interior of the cabinet side wall with j the two rails interconnected for relative movement by a ball bearing intermediate member generally referred to as a ball retainer. Many techniques have been employed to j attach the outer rail member or race to the interior of i the side wall of the drawer cabinet such as for example ! ! self tapping screws or staking. In the case of self : tapping screw mounting care must be taken so the screw is ! 15 not stripped out of its hole due to the repetitive opera- i tion of the drawer and staking requires that great care must be taken to provide good staking so that the stake remains in place after many cycles of the glide.

Since both of the prior art processes require 20 care in assembling the drawer glide to the cabinet side wall, assembly time during the manufacturer of the drawer takes longer than is desirable in providing an economic product. With mounting tabs prewelded to the cabinet side wall or formed integrally therewith during the manufacture 25 of the side wall, the drawer glide mounting system of the present invention can significantly reduce assembly time 2 204366 and therefore manufacturing cost as well as providing a relatively failure proof mount.

Accordingly, the present invention resides in a drawer glide mount for mounting a drawer glide to the interior surface of drawer casing side wall, said drawer glide mount comprising front and rear mounting tabs secured to the interior surface of the side wall of said drawer casing adjacent the front and rear ends theref, one of said mounting tabs including a slot there through and the other of said mounting tabs including a keyslot in the side edge thereof said keyslot comprising an elongated slot of a first vertical dimension and an entrance opening of a lesser vertical dimension, and a drawer glide having a planar extension on one end thereof and an extension having cut-out notches in the top and bottom edges thereof forming a key therein on the other end thereof, the distance between the base of said notches in the top and bottom edges being greater than the entrance opening in said keyslot whereby when said planar extension is inserted into said slot said key must be rotated into said keyslot for locking engagement with said front and rear mounting tabs.

In one especially convenient embodiment of the invention, the mounting of a drawer glide to the interior surface of a drawer cabinet is accomplished by providing a first mounting tab secured to the inner surface of a cabinet side wall adjacent one end thereof which tab includes a keyslot in the outer edge thereof comprising an elongated slot of a first vertical dimension and an entrance opening of a lesser vertical dimension. A second mounting tab is secured to the inner surface of the cabinet side wall adjacent to the other end thereof with the second mounting tab including a slot therethrough which has an upwardly and outwardly diverging side edge in its upper half and a downwardly and outwardly diverging opposite side edge in its lower half. The ball bearing type drawer glide is provided with blade extensions on each end thereof with one blade extension having a stop member extending normal thereto while the other blade extension 20436 has a pair of cut-out notches in the top and bottom edges forming a key, with the distance between the bottom edges of the notches being of a dimension greater than the vertical dimension of the entrance opening in the first 5 mounting tab but less than the vertical dimension of the elongated slot. The first blade extension is inserted into the slot in the second mounting tab until the stop abuts the tab and the glide is rotated slightly to permit the key to enter the keyslot with subsequent rotation back 10 to the vertical of the glide and downward motion of the key in the elongated slot locking the glide to the wall of the cabinet.

In order that the invention can be more clearly understood, a preferred embodiment thereof will now be 15 described, by way of example, with reference to the accompanying drawings in which: Figs. 1, 2 and 3 are perspective views illustrating sequentially the mounting of a drawer glide to the interior surface of a drawer cabinet; Fig. 4 is a perspective view illustrating the key and keyslot of the drawer glide and mounting tab; and Fig. 5 is a front elevation view, partly in section, of the rear mounting tab and drawer cabinet side wall.

Referring now in detail to the drawings wherein like reference characters represent like parts throughout the several views, there is illustrated in Figs. 1 to 3 the assembling of a drawer glide generally designated 10 to the side wall of a drawer cabinet generally designated 30 12. The drawer glide 10 includes an inner rail 14 and an outer rail 16 interconnected by a ball bearing carriage (not shown) and is essentially of the type shown and described in U.S. Patent Specification No. 3,205,025 (Jordan). The conventional drawer glide is modified by 35 providing blade extensions on each end of the outer rail 16. At the rearward end of the glide a planar blade extension 18 includes a stop member 20 thereon extending 20436 4 perpendicular to the plane of the blade member 18. At the other end or front end of the glide the blade extension 22 is somewhat wider than the blade extension 18 and includes square cut notches 24 oppositely disposed in the upper and 5 lower edges of the blade portion 22. The bottoms 26 of the notches 24 are spaced apart a predetermined distance B and form a key, the operation of which will be later described.

The interior surface of the drawer cabinet is 10 provided with a pair of mounting tabs 28 and 30 which are mounted adjacent the rear and front ends of the drawer cabinet side wall respectively, but which could obviously be reversed if the blades on the drawer glide were reversed. As can be best seen in Fig. 5, the rearward 15 mounting tab 28 includes an elongated vertical slot 32 therethrough which has for the upper half of the slot on one side a side edge that diverges upwardly and outwardly to form a ramp 34 and on the other side in its lower half a side edge which diverges downwardly and outwardly to 20 form a ramp 36.

The mounting tab 30 adjacent the front end of the cabinet side wall includes a substantially C-shaped keyslot in the outer edge of the tab comprising an elongated slot portion 38 having a vertical dimension C and an 25 entrance opening 40 to the elongated slot of a lesser vertical dimension A. The entrance opening 40 is shorter than the elongated slot portion 38 by the combined lengths of the longer, upper retaining lip 42 and the shorter, lower retaining lip 44.

As best illustrated in Figs. 2 and 3, in order to mount the drawer glide 10 to the cabinet side wall 12 the blade extension 18 is placed through the aperture 32 until the stop member 20 abuts the mounting tab 28. The entire glide rail is rotated slightly until the blade 35 extension 18 abuts the ramps 34 and 35 which will now permit the upper notch 24 to pass the upper retaining lip 42 and enter the upper portion of the elongated slot 38.

V •' 2Q43&& The guide rail is now rotated toward the vertical (arrow Fig. 2) allowing the lower notch 24 to pass over the lower retaining lip 44 and into a vertical position within the slot 38. The key 22 is then moved downwardly in the slot 5 38 to lock the glide into the mounting tabs. Since the dimension B is greater than the dimension A the key 22 is now locked in place behind the- upper and lower retaining lips 42, 44. The only way that the key 22 can now be removed from the keyslot 38 is to move the key into the 10 longer upper portion of the slot 38 and rotate the key back through the opening 40. Of course, this is not possible when a drawer is positioned and connected to a pair of inner glide rails «■ and thus disengagement of the glides from the mounting tabs is rendered impossible once 15 the drawer is assembled.

As will be seen from the foregoing the drawer glide mount of this invention provides for the quick and simple assembly of a drawer glide to the side wall of a drawer cabinet and provides a locking relationship between 20 the two that will not become loosened or defective during thousands of cycles of the drawer moving in and out of the drawer cabinet. £ * <! v U Oil APR 1986 ■'$ e \ „«.y
